SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 272,167, dated February 13, 1883.

Application filed July 20, 1882. (No model.)

.To all whom it may concern:

Be it known that I, WILLIAM H. SHIPMAN,

a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Spring Bed-Bottoms; and I do hereby declare that the following is a full, clear, and exact description of the invention.

My invention comprises a spring bed-bottom which can be rolled up, or the parallel long slats can be made to slide together, thus in either way making a small compact package for storage or transportation, or the bedbottom will fit different-sized bedsteads,which will be found of the greatest convenience.

In the accompanying drawings, Figure 1 represents a plan or top view when ready for use;,Fig. 2, a plan or top view when contracted and with the springs left olf; Fig'. 3, an end view when rolled up, showing only the lirst and second rows of springs from theY head; Fig. 1.1,an end view when contracted, showing only rst and second rows of springs from the foot.

Similar letters referto similar parts throughout the several views.

In the accompanying drawings, which form part of this specification, A A represent the long slats or strips of the bed-bottom, preferably made of hoop-iron or steel,`on which are fastened the springs E E, which springs are in the form of inverted cones and fastened at the small ends to the strips A A.

B B are the top strips, rigidly fastened to the top of the springs. A

C G and D D are the top end strips, in two pieces, fastened to the-top of springs, but not rigidly.

F F are the cross bottom strips to connect the parallel long strips A A, and are fastened at one 'end of each piece and slide through the brackets h h, thus allowing the strips A A to he slid toward each other, as in Figs. 2 and 4, or to be used on different-sized bedsteads. These strips F F are also exible, made preferably of hand-steel, and when fully extended can be rolled up, as in Fig. 3.

Gr G are small braces, which serve to keep the bed-bottom rectangular. These braces can be dispensed with and one or more long braces, free at one end, substituted.

The upper coils of the springs are to be connectedltogether by chains of small links or long links lf, or other flexible connections.

1n rolling up very narrow beds, the ends of the rolling strips will not meet; therefore I attach a piece, as at g, to the end of each strip by a rivet that will allow it to swing, or by a hinge, so that when the hed is extended for use it can be doubledin, and when the bedhottom is to be rolled up can be used in making the rolling strip long enough to roll up easily and fasten.

In using the bed-bottom on a bedstead of full size it appears as at Fig. 1. 1f desired for a smaller-sized bed, the end top strips, C D, can be loosened in the middle at d, the bedbottom slid to the required size, and the top strips fastened in the holes a a by a clamp or vslid together, the ends ot the strips O and D being at f, and there fastened, while the other end of strip .C is fastened atb, thus securing the bed-bottom in this small compass, as represented in Figs. 2 and 4.

When it is desired to roll up the bed-bottom it is extended to its full width, the top strips, C D,are unfastened atfand swung on e entirely over to the side top strips, B, when d is at c and f is at b, and there fastened and the bed-bottom rolled up, presenting the appearance shown at Fig. 3.

I am aware that prior to my invention bedbottoms have been made to roll up; also, that bed-bottoms have heen constructed to Vshove together. I therefore do not claim the combination, broadly; but

What I do claim as -my invention, and desire to secure by Letters Patent, is,-

1. In a roll-up spring bed-bottom, the small strips g, and said strips being pivotally attached to the rolling or bottom cross-strips, F, substantially as and for the purpose specified.

2. In a roll-up spring bed-bottom, the combination of the slats A and the cross-strips IOO F, said strips lying 4side by side, or parallel, under the bracket h, and the end top strips, C and having one end secured to a Slat, A, and D, substantially as and for the purpose named.

the other end made to slide ou the adjoining slab under the bracket h, substantially as and TM' H' SHIPMAN' 5 for the purpose set forth. Vitnesses:

8. The combination of the slats A, the A. D. SELOVER, strips F, made to slide on the adjoining Slat WM. W. TOWNSEND.
